Title
(DE) VERFAHREN ZUR HERSTELLUNG VON POLYHYDROXYFETTSÄUREAMID-LÖSUNGEN MIT GUTER FARBQUALITÄT UND DEREN VERWENDUNG
(EN) METHOD FOR PREPARING POLYHYDROXY FATTY ACID AMIDE SOLUTIONS OF GOOD COLOR QUALITY AND THEIR USE
(FR) PROCEDE DE PREPARATION DE SOLUTIONS D'AMIDE D'ACIDE GRAS DE POLYHYDROXY DE BONNE QUALITE DE COULEUR ET LEUR UTILISATION
Abstract
(DE)
Beim beschriebenen Verfahren werden die im allgemeinen mehr oder weniger braungefärbten Rohlösungen mit mindestens einer Schwefelverbindung aus der Gruppe der dithionigen Säure in einer wirksamen Menge versetzt, woraus wasserhelle Polyhydroxyfettsäureamid-Produkte resultieren.
(EN)
With the method described, the generally more or less brown-colored crude solutions are mixed with an effective amount of at least one sulfur compound from the hydrosulfurous acid group, yielding water-white polyhydroxy fatty acid amide products.
(FR)
L'invention concerne un procédé selon lequel les solutions brutes de manière générale plus ou moins colorées en brun sont mélangées en quantité efficace avec au moins un composé soufre du groupe de l'acide hyposulfureux, pour donner lieu à des produits transparents en amide d'acide gras de polyhydroxy.
